Sidelink Channel Access Priority Class Table Selection

The patent segments the channel access decision-making process into distinct parameters (sidelink mode, role, cast type, channel type) that can be independently evaluated. This segmentation allows the device to systematically determine the appropriate CAPC table by assessing each parameter separately rather than dealing with an undifferentiated complex decision, thereby improving channel access efficiency while managing device complexity through structured parameter evaluation.

The patent applies dynamics by making the number of LBT sensing slots variable rather than fixed. The device dynamically adjusts the number of sensing slots based on the selected CAPC table, which is determined by current channel conditions, sidelink mode, role, traffic type, and channel type. This dynamic adjustment allows the system to optimize between reliability and latency adaptively - increasing sensing slots when reliability is paramount and reducing them when latency is critical, thus resolving the contradiction between these two parameters.
